HENRY THE EIGHTH OF HORTICULTURE

How to “Make” a New Tree

Visitors to my garden this time of year are often astonished to see me lopping the tops off some of my trees. No, I’m not the Henry the Eighth of horticulture, chopping the head off any tree that no longer meets my fancy. Okay, I AM actually lopping the head off any tree that doesn’t meet my fancy.

I part ways with Ol’ Henry, though, because, first, lopping the head off a tree doesn’t kill it and, second, I graft on a new head. (Something Henry could not do.) A few years after this seemingly brutal operation, the tree looks as chipper as ever. And it has a head that I like better — or else off it comes again.Inserting scions for bark graft

I do this type of grafting, called topworking, mostly on my pear trees, but it could equally be applied to many other kinds of fruit or ornamental trees. Read more

IS REAL SOIL GOING TO POT?

What’s in Your Mix?

That potting soil that you’ve bought for your seedlings and houseplants? It probably has no REAL soil at all in it. Real soil is just too hard to obtain in reliable and uniform quantities for commercial packaging. Soilless mixes, as commercial potting soils are (or should be) called, are a mix of some kind(s) of organic materials along with some aggregate, with possible additions of fertilizer, ground limestone, and a wetting agent.Cats with potted begonias

Organic materials in these mixes help sponge up water and cling to nutrients that might otherwise wash down and out of the pot. Peat moss is the organic material traditionally used in soilless mixes. Although it holds water well, it’s initially hard to wet, which is why wetting agents are sometimes added to soilless mixes. Read more

SOIL PREP

Universal Plant Needs

Although garden plants hail from all corners of the world, they have surprisingly similar soil requirements — best attended to before planting. Simply put, most garden plants need soils that are well-supplied with air (yes, roots must breathe!), water, and nutrients. And one other important ingredient, organic matter (sometimes called humus), that witch’s brew of living and once-living organic materials in various states of decomposition that, in addition to contributing to the just-mentioned needs, also includes a friendly microbial community for optimum plant health.

Aeration must be the first consideration, since plants are unable to utilize nutrients, even in fertile soils, if roots lack access to air. There are two causes for waterlogged soils: either the water table is too high, bringing water up from below; or the soil has pores so small that they cling by capillary action to too much water that falls from above.

Deal with a high water table by either choosing another site for planting, by raising roots above the water table, or by lowering the water table. Growing plants in raised beds is the way to bring roots above a water table. Raised bedsBuild beds high enough to take the roots up out of the water, and wide enough so they don’t dry out too quickly. Read more

CLEAN APPLES, EDIBLE APPLES

Popular Though They May Be . . .

Apples may be a common fruit, second worldwide and in the U.S., bested only by bananas, but they surely are not the easiest ones to grow. At least not over much of this country east of the Rocky Mountains, and here on my farmden. Throughout this area, insects and diseases are ready to pounce on virtually every unsuspecting apple tree.

Pesticides will control these pests but, if needed, are effective only if used rigorously: trees must be regularly and thoroughly doused with the correct material, used at the correct concentration, and applied at the correct times. No wonder the average gardener is daunted at the thought of growing apples!

RDS (ROSEMARY DEATH SYNDROME) SOLVED?

Lack of Water Could Be the Cause

Looks like I’ve done it again. Killed rosemary, the plant. Worse than that, I’ve killed two rosemary plants. And even worse still, drawing on my experiences killing numerous rosemary plants — perhaps you also have killed one or more — I’ve been dispensing my “expertise” on how not to kill rosemary.Rosemary with winter background

My reasoning went like this: Although native to the generally dry climate of the Mediterranean region, roots of rosemary plants in the ground there can reach far and wide in their explorations for water. Not so for rosemary plants that need to live in pots here, where winters are too cold for them outdoors.

To make matters worse, rosemary’s stiff, needle-like leaves don’t signal that the plant is crying out from thirst by wilting. Read more

PLOTTING ALONG

Possible Sources of Anxiety

Especially in years past, I would get a little tense this time of year, because sometime soon I would have to sit down and map out the year’s vegetable garden. As usual, ideas have been bouncing around inside my head for the past few weeks, but the day must come — before April 1st, my date for planting peas — when procrastination must bow to action.Vegetable garden with trellis

When that time comes, I gather together on the kitchen table printouts of the empty beds in my two vegetable gardens, a sharpened pencil, and notes and plans of gardens past. After taking a deep breath, my first order of business, planning for crop rotation, begins. The theory: Plant no vegetable in the same spot sooner than every third year. The rationale: A garden pest might survive the winter to bother the same plant the following year . . . unless the plant happens to be growing elsewhere, in which case the pest starves and dies.

Pests usually are equally fond of all plants in a plant family, so I won’t grow tomatoes, peppers, eggplants, or potatoes (nightshade family) at the same location without waiting three years. Read more

Winter view from indoors

THE GARDEN IN WINTER

Forming Relationships

This may sound crazy but even this far north, winter isn’t a bad time to admire the garden. With leaves and flowers a memory of the past season and a hope for the coming season, the garden is reduced to its bare bones. Not that the wintry scene need be dull or bleak. Good bones give structure to the landscape, knitting it together in some places, dividing it up in others, framing vistas, and providing firm footing for the eyes (figuratively) and feet (literally). Even now.

Three-dimensional forms are what give structure to a landscape. A house usually is the most obvious mass jutting up into space on a property. Too often it’s the only structural element, feebly tied to the landscape with some gumdrop-shaped junipers or yews standing, as if guarding, the foundation.

Winter view from indoorsI have effected a relationship between my yard and my house by building a grape arbor out from the rear wall, then enclosing the ground beneath this arbor with a brick terrace (my house is also brick) edged with a low hedge of potentilla. Similarly, the stone wall supporting what previous were slopes at the front and side of my house flow into the landscape with a contiguous stone wall sweeping out across the yard. Read more

GARDEN FRESH, STILL

Good Only in Theory?

The idea has merit: flowerpots of flavorful herbs decorating windowsills and providing savory additions to meals through the winter. A good part of last season’s garden is packed in the freezer and glistening jars of canned tomatoes line shelves in the basement. The greenhouse is offering a steady supply of lettuce, arugula, and other salad greens.Rosemary against a snowy backdrop

Still, I’m beginning to miss garden-fresh vegetables. Sprinkling some fresh chives on a pan of roasted potatoes might infuse the whole dish with freshness.

The problem is that chives doesn’t thrive on a windowsill, unless the windowsill is very, very sunny. Chives will grow well through the winter with artificial light, but that means a bank of lights permanently poised a few inches above the leaves — so much for the rustic charm of indoor potted herbs. And maybe my taste buds are dulled, but when I snip chives to add to a dish, I take a handful. The plant would need at least a few weeks to recover sufficiently to withstand another harvest.

The same could be said for growing parsley indoors; after each picking, you have to wait too long for another.

I haven’t thrown up my hands at the possibility of growing culinary herbs indoors through the winter. I just have to be very selective in what I grow. Any such herb must pack a lot of flavor into each leaf, survive well indoors, and look pretty. I offer at least two candidates: rosemary and bay laurel. Read more

Flowering kale with pink center

A FLOWER (PERHAPS EDIBLE) NOW AT ITS BEST

A Flower? Not

The same cold weather that has killed most herbaceous plants, or at least battered them ragged, has also brought out the color in flowering kale. Of course, the color is not really that of a flower, but that of a whorl of leaves — glaucous green or purple on the outside of the rosette and becoming more intensely white, pink, or red towards the center. Some varieties are even more ornate, with fringed leaves.Flowering kale with pink center

About this time each year, I make a mental note to plant seeds of flowering kale next season. But I always eventually forget to do it. For the past few weeks, though, I’ve been admiring a planting of flowering kale that has inspired me now to write myself a note about next year’s planting.

My source of inspiration can hardly be called a planting. It’s not a bed full of flowering kale, splashing color all over the place. Nor is it a single file of plants, lining and grabbing attention from a path. Read more

GREAT GIFT IDEAS: BOOKS (NOT ALL JUST) FOR GARDENERS

Fishing, Gardening

“Give a man a fish, and you feed him for a day. Teach a man to fish, and you feed him for a lifetime.” How true, also in gardening. Not to mention the emotional and intellectual gratification, the “companionship with gently growing things . . . [and] exercise which soothes the spirit and develops the deltoid muscles” (C. D. Warner, 1870).

Let’s take teaching the man — or woman — to fish one step further, gardenwise. Lot’s of people wow others with the expertise they have allegedly accrued as evidenced from the mere fact that they’ve spent a number of years, perhaps decades, with their hands in the dirt. I roll my eyes. Flowering plants originated at least 130 million years ago, which is plenty of time to let the trial and error of evolution teach them to grow. Tuck a seed into the ground and it will probably grow.

Better gardening comes from having some understanding of what’s going on beneath the ground and up in the plant. This comes from growing and observing a variety of plants growing in a variety of soils and climates — which is more than is possible in a lifetime.Gardening books

There’s a shortcut: books, a nice adjunct to getting your hands in the dirt. All of which is a roundabout way of my offering recommendations for books about gardening. The right book is also a great gift idea.
